Astronomers have witnessed a rare cosmic event: a massive star that didn’t explode in a spectacular supernova, but instead quietly collapsed into a black hole.

Why they're black: Their gravitational pull is so extreme that even light can't escape Black holes are places where gravity is so powerful that nothing — not even light — can escape. Rather than being ...
